Thanks for the prompt reply. And thanks for clarifying my connection plans.

Hi, thanks for your feedback.
1. The VIN voltage is taken before the Arduino Mega controller, so no problem to power up your Arduino PRO MINI
2. No problem if you power the MEGA with USB without connecting the 12V, the MINI will not turn on because it don’t receive power on the RAW; just connect the 12V to the jack, the MINI turns on and starts working.

Actually I made a slight mistake above… It is a Pro-Mini, NOT a Pro-Micro. I tried attaching an image here for the connection but I don’t see how to do that.

Excellent article. In my application I am wanting to power an Arduino Mega using a 12V 4.5A DC power supply to the barrel/japan jack, and then run an Arduino Pro Micro via the Mega’s Vin line, connecting it to what is called the “RAW” power pin on the Pro Micro. This connection goes into the Pro Micro’s regulator supplying regulated power to run the Pro-Micro, which is only being used to send STEP and DIR values to a stepper motor. The motor itself is powered separately. I have 2 questions:
1. Will this work, without putting too much stress on the Mega’s regulator?
2. Would it be problematic if for instance, I happen to inadvertently plug in the Mega to a USB cable, WITHOUT it also being already connected to the 12V power supply at the Barrel/Japan jack? If I read your article correctly, the Vin is not connected to power via the USB jack, meaning that the Pro-Micro, would simply not be powered in this case?
Thanks for a great and informative article.

David
